Dear dear sister, i dont even know you but I want to give you a hug
I too have 2 small children and a husband (albeit not an elder, but a former MS) still in as well as most of both our families. Take it slow and gentle with the husband, you might get somewhere. But respect free choice.
I told my husband my doubts and that I can no longer in good conscience share in the ministry. I continue to go to some meetings with him and the kids, and allow him to teach them "the truth", but I do not instigate anything. If he brings things up, I am honest.
f things carry on, as my children grow older and perhaps are considering baptism, I will give them more information from "the other side" I will also not oppose them in extracurricular activities (sports outside of school etc) and I honestly dont think their Dad will either.
As others have said, there is no need to make some sudden obvious stand, take your time love. Just love your family and follow your conscience.
Love, SkyGreen
